SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 610,369, datedSeptember 6, 1898. Ap li ation m d December 17,1897. Serial No. 662,298.(No model.)

To all whom it may concern.-

Be it known that I, CHARLES H. RAYMOND, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inSash-Locks, of which the following is a full and complete specification,such as will enable those skilled in the art to which it appertains tomake and use the same.

The sash-lock forming the subject of this invention is chiefly intendedfor car-windows, although not restricted to such use, and has for itsobject to provide a readily operated device for holding and looking asash at any point within its limit of movement.

The invention consists in the features of construction'and combinationsof parts hereinafter fully described and specifically claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by the same numerals of reference ineach of the views, and in which- Figure 1 is a front elevation, partlyin section, of a portion of a window frame and sash provided with thisimprovement. Fig. 2 is a vertical section showing an end elevation ofthe sash-lock, and Fig. 3 is a horizontal section on the line 3 3 ofFig. 1.

This sash-lock consists of a rack and a rotatable toothed wheelintermeshing therewith and having a spring-actuated detent for holdingit against rotation. The parts are interchangeable-that is to say, therack can be secured to the sash or window-frame, and

likewise the rotatable toothed wheel, so that when the detent is out ofengagement therewith the sash is free to move, but is locked when thewheel is held by the detent.

In the drawings forming part of this specification the rack is shown asapplied to the sash and the wheel to the frame and will now bedescribed. I

1 indicates the window-frame, and 2 a sash sliding therein, 3 being theinner stop. On the inner face of the inner stop a rack-bar 4: isfastened, being set into the same so that it is flush therewith. Therack-bar is narrower than the stop 3 to form a groove 5 between theouter side of bar 4. and the framepiece 6. The sash 2 is provided with aplate 7, set into the same to be flush therewith, but provided with abent outer end or lug 8, situated within the groove 5 to preserve andin-' sure the proper relative positions of the sash and rack-bar, itbeing noted that otherwise, by reason of shrinkage of the sash, thelooking device carried thereby might be taken out of engagement withsaid rack-bar.

The locking device consists of a casing 9, fastened to the side rail ofthe sash and having a rotatable toothed wheel projecting from one sidethereof and intermeshing with the rack-bar 4, said wheel being looseupon a stud 11, projecting from the side plate of the casing. Within thecasing is a spring-actuated detent 12, operated by a handle 13 from theoutside. The detent consists of a frame sliding in suitable guides, witha tooth 14: at

one end to engage the wheel, while a spring forces the tooth intoengagement. The handle is attached to the other end and eX- tendsthrough a slot in the plate.

It is seen that by retracting the tooth 14: the sash is free to slide,since the wheel rotates. When the sash is adjusted, the detent isreleased, and its tooth, holding the wheel against rotation, preventsthe sliding of the sash and effectually locks the same.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- The combination with the frame having a rack-barsecured to the inner face of the inner stop, of a sliding sash havingaplate provided with a lug or projection engaging the rear edge of saidbar, a casing having a rotatable toothed wheel intermeshing with saidtoothed rack, a sliding detent having a tooth to engage said wheel, aspring pressing said tooth into engagement with the wheel, and a handlesecured to the detent and extending through a slot in the plate of thecasing, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 14th day ofDecember, 1897.

CHAS. H. RAYMOND.
